According to Bob Nightengale of USA Today, the Rangers are "strongly pursuing" Royals closer Kelvin Herrera.

Kansas City appears poised for an organizational rebuild, so Herrera -- a free agent next winter -- can probably be had with the right match of young talent. Joel Sherman of the New York Post reported on the first day of the Winter Meetings that the Royals were at least "fielding interest" in the 27-year-old right-hander. Herrera struggled to a 4.25 ERA over 59 2/3 innings in 2017, but he put up a dominant 2.30 ERA with 209 strikeouts in 211 2/3 innings between 2014-2016. Thu, Dec 14, 2017 03:45:00 AM

Joel Sherman of the New York Post reports that the Royals are fielding interest in reliever Kelvin Herrera.

The Royals could be shifting into a rebuild, so it makes sense to listen on Herrera, who will hit free agency after 2018. They'd be selling low, though, as Herrera missed time with a forearm strain this past season and proved to be a disappointment in the closer role while posting a 4.25 ERA and 56/20 K/BB ratio over 59 1/3 innings. He made $5.325 million in 2017 and will likely see that number jump to over $8 million next year. Mon, Dec 11, 2017 11:26:00 AM

Kelvin Herrera pitched a scoreless seventh inning for his fourth hold Friday against the Diamondbacks.

No one has told Ned Yost that the Royals have been eliminated. Not only is he refusing to go to his youngsters in the lineup, but he's had Herrera pitch three innings the last four days, which seems pretty risky given his recent bouts with forearm soreness. Herrera has looked better of late, but it'd be a shame if he suffered a setback during the final week of the season. Fri, Sep 29, 2017 11:42:00 PM

Duffy underwent surgery in October to remove "loose bodies" of cartilage and bone fragments from his elbow, but he's already a few weeks into a throwing program and is currently long-tossing from a distance of 100 feet. He should be fine for spring training. "I wish I had done this [surgery] a while ago," said Duffy. "[Trainer] Nick Kenney had been on me to get it done, but I kept feeling like I could manage my way through it." Duffy posted a 3.81 ERA and 130/41 K/BB ratio over 146 1/3 innings last season.
